Chris Pratt: "I'm Never Going to Be Fat Again"

The actor talks to Men's Health about his yo-yo weight in the past.

Chris Pratt's weight has yo-yoed throughout his career, and he spoke about the reasons for the fluctuation in Men's Health U.K.'s July issue.

"I put on weight because I'd fallen in love with a woman [Anna Faris] who loved to feed her man," says Pratt. "I was her little Hansel out in the woods and she was fattening me up to put me in the fire. It was like Momma Bear and Papa Bear. She would eat a little bit, I would eat all of mine and the rest of hers."

He says he also wanted to gain weight for his role in Parks and Recreation.

"I announced it to the whole cast, and then it became a bit of a game: how fat can I get and how fast," says Pratt. "I would eat four burgers at every read. I became really fat and got up to almost 300lb." The extra weight affected him emotionally and physically. "I had real health issues that were affecting me in a major way. It's bad for your heart, your skin, your system, your spirit."

The actor's weigh continued to fluctuate depending on which role he was preparing to play, until he decided once and for all to stop.

"I'd gone back and forth, lost weight for Moneyball, got fat again, then trimmed down for Zero Dark Thirty, then gained it all back again for Andy," said Pratt. "That's when I saw Zero Dark Thirty and right after walking out I was like: 'I'm going to get in shape and I'm never going to be fat again.'"

"When I was fat and unhappy, the only moments of respite I got were when I was eating," he said. "Now mealtimes are sometimes lame, because that's the way it can be when you're eating healthily. But all the time between meals, I feel great."
